Verification and Validation Program for a Distributed Computer System for Safety Application

Abstract The importance of a Verification & Validation (V&V) program, to affirm the reliable operation of computer systems in real time safety applications, is widely recognized. To ensure consistent, traceable, and auditable high performance of the individuals involved in the V&V program, several pragmatic issues such as quality of documentation, details and staging of activities, etc. should be resolved prior to the practical application of the V&V program This paper presents the V&V program established for the development of 16-bit, microprocessor-based distributed safety systems, for application to the safety of nuclear power plants and especially tailored for the Italian plants. The development project, which is under the responsibility of Westinghouse, has the participation of various Italian organizations, each contributing in different areas of expertise
